I was out in the backyard of the house at ((deleted)) 39th Ave. E. in Madison Park area of Seattle, looking at the stars and then observed a flash followed by another flash and then a third that were separated by 3-4 seconds of darkness. The flashes were quite far off and looked like stars, it was clearly not a plane or helicopter. The first three flashes could have been part of a single line.

However then there was a fourth flash that was at right angles to that line.

And this is what freaked me...and I got goose bumps. Nothing known can do what this flashing "object" did that I know about.
